rough idle and some other issues
Rought idle has been chasing me for a long time now. Engine seems to vibrate too much and sometimes it seems like it misfires, although all 6 coils were replaced with updated ones and there are no codes. Cleaning my TB doesn't seem to help. Overall engine doesn't sound as smooth as before. Any idea what else could cause it?
Also, gas milage seems to go down with every tank of gas. Honestly, have no idea what the cause could be, used to get 280-300 miles on a tank, barely 260-270 nowadays.
Any thoughts on this?
btw, my mods: berk intake with K&N, and FrankenCar catback.

I was thinking about getting a new MAF as well, but I had this going on for a long time and if it was the MAF I'd expect it to go out by now. Anyway, let me know if a new MAF changes anything for you

How did you clean your injectors? Did you just use injector cleaner that you purchase at the autoshops? Those really don't get everything out the injectors, especially if its been a while since you last had them serviced. You might have one that is still bad. You should try doing a fuel pressure test to actually see if they are working properly

bringing this topic back to life...
thanks for the reply and advice. I used BG 44k to clean the injectors and seemed like it didn't help at all. What are other inexpensive options to clean them? Fuel pressure test sounds good too.
I hope not.
